AutoTest: Support some ctest settings

Add some useful settings for ctest based testing. Adapt output
parser accordingly to get at least relevant output and display
significant information inside the visual display.
Current implementation loses or mixes some information when
running jobs in parallel.
Complete output is still available inside the text display.
